980/1550nm Polarization Maintaining Pm Fused Wdm

980/1550nm Polarization Maintaining PM Fused WDMProduct DescriptionLightwit Photonics uses unique fusing technique and polarization maintaining fiber to build the 980/1550nm polarization maintaining fused WDM. It features low excess loss, small size and high polarization extinction ratio. PM fused WDM is widely used for fiber laser,optical sensors and optical gyro.This product can also be used to multiplex other wavelengths. including 980/1030 nm (pulsed laser applications) and 1064/1550 nm (Erbium-Ytterbium pumping). Low power (300 mW, 500 mW) and high power (20W) handling are available.They are ideal for polarization maintaining fiber amplifiers, fiber lasers, and high speed communication system and instrumentation applications.  FeaturesLow Insertion LossLow Excess LossLow PDLGood DirectivityGood environmental StabilityVarious Coupling RatioCompact SizeStandard/Flattened/Broadband/Star/TreeApplicationsOptical Fiber Communication SystemsFiber LaserPassive Optical Network (PON)Optical AmplifiersOptical Access Networks/LANMonitoring SystemsOptical Fiber SensorSpecificationarameterUnitSpecificationsOperating Wavelengthnm980/1550Operating bandwidthnm980±10, 1528~1565Max.

Above specifications are for device without connector, and the PM WDM device is both axis working, no axis can be blocked; default test extinction ratio is on the slow axis. All parameters are tested at room temperature.2. For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower and ER will be 2dB lower. Power transmits through the connector less than 2W.The default connector key is aligned to slow axis.3. For >10W high power applications, we will use heat sink package, contact Lightwit Photonics for details.4. If there is pulse application, please be sure to inform us of pulse energy and peak power.Order Information   1234567PortOperating WavelengthPower HandlingFiber TypePigtails DiameterFiber LengthConnector102:1x2202:2x295:980/1550nm65:1064/1550nm93:980/1030nm96:980/1064nm35:1310/1550nmXX:OthersL:
